FAQ
-
What is the typical response time of the ADM52C/CE1 S2 contact outputs?
The module responds within 10 ms under normal conditions. -
Are the contact outputs isolated from each other?
Yes, each channel is isolated to prevent cross-talk and ensure reliable operation. -
What types of loads can the module control directly?
It is suitable for resistive and inductive loads within rated limits (e.g., relays, solenoids, alarms). -
Can the module handle inductive loads without additional protection?
For inductive loads, external snubbers or flyback diodes are recommended to protect contacts. -
How is the module connected within the Yokogawa system?
It mounts on the system rack baseplate and interfaces with the processor via the backplane bus. -
Does the module support fail-safe output states?
Yes, it can be configured to switch to predefined fail-safe states during system failures. -
What is the maximum switching current supported per channel?
Up to 2 A at 24 V DC (resistive load), depending on system configuration. -
Is hot-swapping supported for this module?
It depends on the system rack configuration; typically, Yokogawa modules support guided replacement under controlled conditions. -
How does the module ensure EMC compliance?
